ME60 Special Topic - CGN V1.0

Carrier-grade NAT (CGN) is a large-scale NAT that delivers statistical reuse of public IPv4 addresses through large-scale private IPv4 address deployment. The use of CGN can improve the usage of IPv4 addresses, which solves IPv4 address exhaustion to a great extent and leaves more time for IPv6 transition. Mainstream IPv6 evolution solutions, such as dual-stack + NAT444 and DS-Lite solutions, have all introduced CGN.
